Title: Reducing Howling in a communication system by limiting Receiving Radio Speaker volume when receiving radio is sufficiently close to the sending radio.
Inventor: GEAN NISSIM
IPC: H04B3/20
Filed: 2008-12-18
Abstract: A method for reducing howling in a half-duplex communication system containing radios is presented. Prior to receiving an audio signal transmitted from a sending radio to receiving radios in the half-duplex communication system, the sending radio emits a talk-permit tone (audio tone) from a speaker. If any receiving radios are sufficiently close to the sending radio, they receive the talk-permit tone (audio tone) on their microphones. In that event, those radios, detect whether the talk-permit tone exceeds a predetermined threshold, and if that result occurs, the volume of each detecting radio speaker is automatically limited to a maximum allowed volume. Half duplex communication systems minimize howling because each system device opens only one channel (one direction — receive or transmit) at a time, but howling can still occur when two devices are sufficiently close to produce acoustic coupling. The present invention minimizes howling as described above.

Filed: 1934-04-04
Abstract: Halogenated di- and tri-phenyl methane are obtained by the Friedel-Craft process by condensing a halogenated benzyl or benzal chloride with a halogenated or unsubstituted benzene in presence of aluminium chloride.  According to examples monochlorobenzyl chloride and monochor benzene are condensed to give a dichlor-diphenylmethane; trichlorbenzylchloride and benzene are condensed to give a trichlordiphenyl methane; dichlorbenzyl chloride and chlorbenzene give a trichlordiphenylmethane; trichlorbenzyl chloride and monochlorbenzene give a tetrachlordiphenylmethane; dichlorbenzyl chloride and dichlorbenzene give a tetrachlordiphenylmethane; trichlorbenzylchloride and dichlorbenzene give a pentachlordiphenylmethane; trichlorbenzyl chloride and trichlorbenzene give a hexachlordiphenylmethane; the corresponding chlorinated triphenyl methane derivatives are also obtained from trichlorbenzal chloride and benzene, dichlorbenzal chloride and monochlorbenzene, trichlorbenzal chloride and chlorbenzene.  The products are non-crystalline and consist of mixtures of isomers of which the main constituents are those specified in the examples, and are to be used as dielectric, insulating and cooling media in electrical apparatus such as transformers, switches, capacitors, cables, bushings and junction boxes.  They are mostly non-inflammable, and those compounds or mixtures of compounds containing different proportions of halogen, which contain a total molecular proportion of hydrogen equal to that of the halogen, produce the non-inflammable hydrogen chloride when subjected to an electric arc.  They may be employed mixed with trichlorbenzene, chlorinated diphenyl and the like, in electrical apparatus. Specifications 413,596, [Group XXXVI], 433,070, and 433,071 are referred to.

Patent GB-493471-A (GB)
Title: Extendible and contractible strut or jack for aerial machines
IPC: B64C25/22
Filed: 1937-04-10
Abstract: 493,471. Fluid-actuated apparatus; pneumatic single-stroke apparatus. TURNERS MOTOR MANUFACTURING CO., Ltd., and MILNER, H. C. April 10, 1937, No. 10255. [Class 69 (ii)] [Also in Groups XXVIII and XXXIII] In a fluid-actuated jack having means for locking the piston in its extreme positions in the cylinder, the locking means being carried by the piston, and comprising a group of locking elements and an auxiliary piston, the arrangement is such that the latter has a movement relative to the main piston when said elements arrive at the locking rebate whereby the locking is effected by a positive action. The piston 7 carries two sets of radially-arranged locking pins 1 having coned heads 5 to engage recesses 4 in the cylinder ; auxiliary pistons 9, 10 sliding in the piston 7 are pressed apart by a spring 18. In the contracted position shown, the left-hand set of pins 1 engage the corresponding recesses 4 to lock the jack against extension ; further contraction is limited by contact of the end face 6 of the piston with the end wall 8 of the cylinder ; the pins 1 are held in locking position by the piston 9 engaging their inner ends 11 which are rounded or coned. When pressure fluid is admitted through left-hand port 20 the piston 9 is displaced to the right out of contact with the inner ends 11 of the pins 1; the piston 7 then begins to move to the right, and the locking pins are forced inwardly into inoperative position against the springs 12. The piston 9 abuts the piston 10 and thus the latter is subjected to the pressure of the fluid, so that when the piston 7 reaches its right-hand position, the piston 10 moves to the right to force the righthand set of locking pins 1 into the corresponding recesses, this being aided by the springs 12. Pressure fluid supplied through right-hand port 20 gains access to the piston 10 through annular space 27, ports 21 and chamber 26. Valves 35 allow liquid to escape from between the pistons 9, 10. When the parts are in the contracted position, the piston 9 can be moved to release the pins 1 by means of a sliding member 30 and lever 34 operated by a cable, rod &c., thus permitting the jack to extend without supplying it with pressure fluid. The locking pins may be replaced by balls or other expedients. The jack is applicable to retractable undercarriages, flap-operating gear &c. of aircraft.

Abstract: 566,132. Discharge lamps. BRITISH THOMSON-HOUSTON CO., Ltd. June 25, 1943, No. 10269. Convention date, June 29, 1942. [Class 39 (i)] [Also in Groups II, VIII, XI and XXII] Anti-glow material, such as aluminium or aluminium oxide, is painted on to a strip of metal before the strip is shaped to form electrodes of a glow discharge device ; the inconvenience of painting the finished electrode is thereby avoided. The strip 11, Fig. 1, is drawn from roll 10 by motor driven rollers 13 and passed between applicator rollers 15, 16, the top roller 15 being rubber and the bottom roller 16 dipping into a bath of anti-glow material, such as aluminium paint. A narrow margin at each edge of the strip is left free from paint. The strip then passes over three electrodes 17, 18, 19 supplied with heating current from step-down transformer 26 so as to bake the paint. The electrodes may be artificially cooled. Finally, the strip is wound on to motor-driven roll 23. The strip is then punched to form electrodes, for example, of the shape shown in Fig. 3, and two such electrodes are washed and mounted in beehive fashion in the discharge envelope and fired in moist hydrogen to remove the binder.
